1. My system already works fine.
2. The default styling of Labradoc doesn't suit me. The blue/purple links and left-aligned text have a 2005ish look to me. Those would presumably be pretty easy to fix with a CSS overlay of some sort, but that would require a little tweaking.
But still, Labradoc looks like pretty much the same solution that I came up with, so I like it!
One suggestion: make the example have a link or screenshots to something that shows the Markdown side of things. Is there an editor? What does it look like? Even a screenshot tour would help lure people in.
